Hi, Sometimes I can see messages from the mailing list that have no Reply-To header. For example, this is the headers from a recent email from the ML: Delivered-To: andrey.semashev@gmail.com Received: by 10.223.171.174 with SMTP id s43csp1184445wrc; Tue, 21 Mar 2017 04:54:11 -0700 (PDT) X-Received: by 10.233.239.75 with SMTP id d72mr28079608qkg.313.1490097251746; Tue, 21 Mar 2017 04:54:11 -0700 (PDT) Return-Path: <andrey.a.davydov@gmail.com> Received: from mail-qk0-x233.google.com (mail-qk0-x233.google.com.

To: boost@lists.boost.org Cc: Andrey Semashev <andrey.semashev@gmail.com> Content-Type: multipart/alternative; boundary=001a1146f4805976ff054b3c4d27 As a result, when I press Reply, the reply is addressed to the original email sender instead of the mailing list, which is really easy to miss before sending the message. Is it possible to ensure that every email from the ML contains boost@lists.boost.org in its Reply-To header? PS: I'm not a guru in email protocols, so if there is another more appropriate way of doing this then that would be fine with me.
